It could be A9.I doubt that this manufacturer has the resources to procure a proprietary powder so is likely a canister powder. I don't know of any other

The lots of A9 previously made in Belgium were very round and dull/dark. Also very tiny. The newer USA lots made by St. Marks in Florida have granules that are a bit flattened and a bit of a shimmer in the right light. Very tiny granules Lots of A9 have been made by different manufacturers over the years and have different looks.
